Operation is smooth, with velvet soft focus ring, and soft clickable aperture ring. And looks nice on top! Although not a Series 1 lens, it's a well build lens. A little on the heavy side, but solid metal build with build-in hood. You can drop this thing, and it would likely damage the pavement and not the lens.
Picture quality is fairly excellent. A little color fringe on the sides, but sharp overall (a little less wide open), no vignetting and nice colors without to much editing. Although I have no picture to proof it, the lens seems to create pleasant bokeh. In any way, a pleasure to use this lens. Vivitar knew what they were purchasing...
